I am thirty years old and have been diagnosed with tachycardia for five years. I donate blood to the Red Cross every sixty days and have recently noticed that my heart rate increases and beats much harder after I donate. Is it safe to donate blood with tachycardia? What might cause my increased heart rate and more deliberate heart beats? Thanks.
Dear Don
Anemia (low blood counts) can cause tachycardia. You should see a doctor and make sure that you are not anemic before continuing to donate blood.
